PseudoRover GPS receiver
First Claim
1. A method of determining the respective positions of a plurality of remotely distributed locations in a seismic data acquisition system having a seismic data communication network, said method comprising the steps of:
- positioning a GPS antenna module having minimal antenna signal processing capacity at each position in said seismic data acquisition system to be determined;
providing a base GPS receiver having a base antenna and full GPS signal processing and memory capacity;
receiving GPS satellite signals by said antenna modules;
processing said GPS satellite signals by said antenna modules for transmission to said base GPS receiver; and
,determining and recording the global position of each said antenna module by said base GPS receiver.

Abstract
A network distributed seismic data acquisition system comprises seismic receivers, connected to remote data acquisition modules, receiver lines, base line modules base lines, a central recording system and a seismic source event generation unit. A Global positioning system antenna is positioned at many or all seismic receiver take-out points. Each antenna is supported by minimal antenna signal processing circuitry for transmitting antenna reception to a base GPS receiver having full GPS signal processing capability for determining the distinctive global position of each antenna.
